IPC: H02P27/06
Filed: 1988-06-08
Abstract: PURPOSE:To prevent an overcurrent from flowing to a power rectifier by suppressing the firing angle of a thyristor to a level in which a power rectifier overcurrent detector does not operate if a load current is abruptly varied or a voltage feedback signal is abruptly changed. CONSTITUTION:Assume that a feedback signal to a converter 2 is abruptly reduced due to the rapid load change of an inverter 4 or the erroneous operation of a voltage feedback circuit. In this case, a phase circuit 15 increases an ignition pulse signal 15a to the converter 2 in response to the abrupt decrease in the feedback signal. The increased ignition signal 15a is input to an ignition angle limiter 31, which obtains its detecting level. The limiter 31 is variably controlled at its ignition angle which does not exceeding the maximum allowable current of the converter 2 according to the detecting level, and outputs an ignition angle limiter value 31a to the converter 2.
